Helen Bertelli knew her homemade treasure hunts were popular with the kids in her Wake Forest neighborhood. It turns out that they are popular with kids all across the country.

Bertelli's Clued in Kids, which I featured on Go Ask Mom in May, can now be found in stores around the United States. Bertelli, a mom of two, also will be exhibiting at the Christmas Carousel Market at the N.C. State Fairgrounds over Thanksgiving weekend and the Downtown Cary Food & Flea Christmas Market on Dec. 14.

Bertelli launched the business a year ago after working for more than two years to develop the concept and learn everything from accounting to design work.

Bertelli loved treasure hunts as a child. To keep her kids occupied and away from a screen, she created some for them. Eventually, their friends got involved in the fun. Bertelli's own mom convinced her she might have something worth selling.

The hunts are designed for kids ages 4 to 12 and work best with anywhere between one and 10 kids. It takes an adult or older child just eight minutes to set up.

The hunts send kids searching for clues around a house. To get from one clue to the next, they answer questions and puzzles. The clues are typically found in common parts of a house - by the silverware, the bikes or the door bell, for instance.

Bertelli has themed and holiday hunts. These make great stocking stuffers or, if you buy three or more from her site, you can get a treasure chest to store them in under the tree.
